A creator of any niche can become your referral, yet there are three restrictions when it comes to the social media account they need to connect in order to earn you a free Starter Plan credit:
HypeAuditor currently only supports Instagram, TikTok, and YouTube accounts within the referral program.
Only accounts with more than 1,000 followers can be connected.
HypeAuditor operates with publicly available data, so a creator with a private or restricted account would not be able to connect it.
Make sure any creator you invite meets these requirements so their sign-up counts toward your referral balance.
